Photoeye sensor uses changes in light intensity to be converted into electrical signal changes to achieve control. In general, Photoeye sensor consists of three parts, which are divided into: transmitter, receiver and detection circuit.

The photoeye sensor manufacturer tells you that the transmitter is aimed at the target and emits light beams. The emitted light beams generally come from semiconductor light sources, light-emitting diodes (LED), laser diodes and infrared emitting diodes. The beam is emitted uninterrupted, or the pulse width is changed. The Photoeye sensor manufacturer tells you that the receiver is composed of photodiodes, phototransistors, and photocells. In front of the receiver, optical components such as lens and aperture are installed. Behind it is the detection circuit, which can filter out the effective signal and apply the signal. In addition, there are emitting plates and optical fibers in the structural elements of the photoelectric switch.
The triangular reflector is a strong launching device. The Photoeye sensor manufacturer tells you that it is composed of a small triangular pyramid reflecting material, which can make the light beam accurately return from the reflector, which is of practical significance. It can change the emission angle from 0 to 25 relative to the optical axis, so that the light beam is almost from an emission line, and after reflection, it still returns from this reflection line.
Because the application of Photoeye sensor covers a wide range of fields, its research and development have attracted great attention in the world.
